Secretomes

Secretomes refer to the full range of bioactive molecules secreted by cells—especially stem cells—into their surrounding environment.

What Are Secretomes?

Secretomes are a powerful collection of molecules secreted by stem cells and other regenerative cells. They include:

  • Exosomes

  • Cytokines

  • Growth Factors

  • RNA messengers

  • Other signaling proteins

These molecules influence your body’s natural repair processes, reduce inflammation, support immune function, and accelerate tissue regeneration.Why Use Secretomes in Therapy?
Traditional stem cell therapy involves harvesting, culturing, and reinjecting live cells. While promising, these therapies come with challenges like storage, immune compatibility, and cell viability.
Secretome therapy offers:

  • Cell-Free Convenience: Easier to store and apply than live cells.

  • Reduced Risk: No risk of uncontrolled cell growth or rejection.

  • High Potency: Concentrated regenerative signals without dilution or decay.

Why Secretomes Matter

Secretome-based therapies are gaining momentum because:

  • They are cell-free, reducing the risk of tumor formation or immune rejection.

  • They carry the benefits of stem cells without the complexities of using live cells.

  • They are more stable and easier to store, ship, and administer.

In short, Secretomes = the healing power of stem cells, simplified and safer.

How Are Secretomes Used?

Clinics and researchers use secretomes for:

  • Skin rejuvenation

  • Orthopedic recovery

  • Immune support

  • Neurological and cardiovascular healing

  • Inflammatory condition treatment

These therapies are often administered topically, via injection, or through IV infusions, depending on the treatment goal.
